Jenny McCarthy may be singled out again, but that doesn't mean she's spending that time at home!

One day after the star, 39, confirmed to Us Weekly that she and her boyfriend of four months, football player Brian Urlacher, had called it quits, the blonde stunner hit up Sin City for a night out with her girls.

While flaunting her legs in a short black mini dress paired with sky-high Christian Louboutin heels, the newly single star and her friends ate at Las Vegas' STACK Restaurant before heading over to 1 OAK nightclub at the Mirage Hotel & Casino where they danced the night away till 3 a.m.

Out on the red carpet, the model, who posed nude for Playboy's July/August issue, told Us that despite her breakup, she's keeping her head held high. "You know, I"m a hopeless romantic. I always think positively. I'm looking forward to my next adventures and what's ahead."

Speaking of new ventures, the star shared what's currently in store for her. "I have a new book coming out in October and a new series coming up on NBC. So I have a lot of stuff upcoming. I just moved to Chicago. My son is really happy, I'm happy, it's good."

McCarthy, who is a Chicago native, was married to actor/director John Mallory Asher from 2001 to 2005; they have a son, Evan, 10. She also had a long-term relationship with Jim Carrey from 2005 to 2010.

On Thursday, she said that she and Urlacher, a line back for the Chicago Bears, will remain friends. "[We've] decided to turn our romance into an amazing friendship. I will continue to be the biggest cheerleader for him. Go, Bears!"
